Area Forecast Discussion National Weather Service San Francisco Bay Area 1012 PM PST Sat Dec 7 2019

SYNOPSIS. Scattered showers will continue overnight and into Sunday morning. Showers will end from north to south on Sunday afternoon. Dry conditions are then forecast for most of next week, except for light rain chances late Tuesday and Tuesday night and then again late in the week. Temperatures will be near seasonal averages through next week.

DISCUSSION. As of 8:45 PM PST . A line of intense showers associated with an upper trough near the northern California coast produced very heavy rain in San Francisco this afternoon. Rain rates in excess of an inch per hour in the City resulted in widespread street flooding. Heavy downpours occurred locally elsewhere in the Bay Area during mid to late afternoon. Showers have since tapered off and radar shows most shower activity is currently across Monterey and San Benito Counties, with only widely scattered showers farther to the north. Expect some showers to produce brief heavy downpours overnight, mainly across the southern half of our forecast area. Heavy rain across the Kincade burn scar appears unlikely from this point forward, and so the Flash Flood Watch for that area in Sonoma County will be allowed to expire at 10 pm.

Gusty south to southwest winds occurred today as a surface low tracked inland near the CA/OR border. Wind gusts up to 50 mph were common at higher elevations this afternoon and local gusts up to 40 mph occurred near the coast. Winds have been gradually subsiding this evening, and a trend towards decreasing winds is expected to continue for the remainder of the evening as the surface low moves northeast and weakens.

Scattered showers will continue into Sunday morning as the upper trough gradually tracks to the southeast across California. Showers will taper off and end after the upper trough axis passes, which is expected to occur in the North Bay by late morning and across the southern portions of our area by late afternoon. Additional rainfall through Sunday is forecast to range from a quarter to half inch in most areas, with locally higher amounts possible in the coastal hills.

A high amplitude ridge is forecast to build over California on Monday and this will result in dry conditions across our entire region through at least Tuesday morning. A weak system is then forecast to bring a brief period of light precipitation to northern California from late Tuesday afternoon through Tuesday night. Rain chances during this time frame will be highest across the North Bay, with lower chances farther to the south. A broad upper ridge is then expected to build off the southern California Coast during the second half of next week, resulting in generally dry and mild conditions except for the potential for another brief round of light rain in the North Bay late in the week.

AVIATION. as of 10:12 PM PST Saturday . MVFR except IFR-LIFR in showers with an amplifying mid to upper level trough tonight and Sunday morning. Dry weather returning Sunday afternoon and night.

Vicinity of KSFO . MVFR ceiling with showers tonight and Sunday morning. Southwest wind tonight shifting to west by late Sunday morning.

SFO Bridge Approach . Similar to KSFO.

Monterey Bay Terminals . VFR-MVFR ceilings with showers, possibly heavy at times, surface wind from the south. Winds shifting to west to northwest by Sunday afternoon.

MARINE. as of 9:57 PM PST Saturday . South to southwest winds will diminish through this evening. A moderate west swell continues through Sunday. Wind waves will ease tonight as winds diminish.

There are five sources. 1) Documents and manuals from a variety of sources. These have not been checked for accuracy and in many cases have not even been read by anyone associated with L-36.com. I have no idea of they are useful or accurate, I leave that to the reader. 2) Articles others have written and submitted.

These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
